AUTOMATIC STOP-MOTION T0 ATTACH TO A COTTON-CARD.

Specification of Letters Patent.

Application filed August 29. 1911.

Patented Oct. '15, 1912.

Serial No. 646,758.

To all whom it may concern:

Be it known that I, VALKER WV. GREN- sHAW, a citizen of the UnitedStates, residing at Rockhill, in the county of York and State of SouthCarolina, have invented certain new and useful Improvements in AutomaticStop-Motions to Attach to Cotton Cards, of which the following is aspecification.

This invention has relation to new and useful improvements in automaticstop motion to attach to a cotton card.

The main object of my invention is to prevent choking of a cotton cardon account of too much cotton entering the same and will also prohibitexcessive doublings.

A further object of my device is to preview my invention consists of thenovel feacard, which objects would damage the card wire, licker-in ormoat knives.

By the use of my improvements, the screens, moat knives or feed platesmay not be removed from their proper settings.

A further object of my invention is to provide a device of this naturethat will be simple in construction, cheap to manufacture and durable asto wear and tear.

With the foregoing and other objects in view my invention consists ofthe novel features of construction, combination and arrangement of partsas are described in this specification, illustrated in the accompanyingdrawings forming a part thereof and particularly pointed out in theappended claim.

Reference being had to the drawings: Figure 1 is a side elevational viewof my invention. Fig. 2 is a side elevational view of my invention,looking at the opposite side to that which is illustrated in Fig. 1,parts being broken away. Fig. 3 is a top plan View of my invention. Fig.4 is a vertical, transverse sectional view taken on the line 4-4 of Fig.3. Fig. 5 is a perspective view of a slide bearing, utilized in theoperation of the device.

Referring more particularly to the drawings in which like numeralsdesignate like parts throughout, my invention is described as follows:The cotton 1 which rests upon the feed plate 2 passes under the roller 3mounted for rotation in the bearings 4, which bearings extend upwardfrom the Held to one end of said roller 3 is a large beveled gear 6which intermeshes with a small beveled gear 7 held upon the inner end ofa shaft,

which is in turn held for rotation in an adjustable bearing 8 near itsinner end. When too much cotton or any solid object begins to pass undersaid feed roller 3 it will raise said roller together with its spindle9, which action will raise rods 10 by pressing upward against anadjustable extension 11. This action will raise the adjacent end of anarm 12, which arm is pivoted to a transverse shaft 13 which extendsthrough the frame of the card and acts as a bearing or support for saidarms. Secured to the opposite end of the arm 12 is a vertical arm 14,the upper end of which extends through an opening 15 in the stand 16,which stand supports the slide bearing 17 of shaft 18. Said shaft 18extends through an opening 19 in said slide bearing 17 and when the armlet is drawn downward by the action of such arm 12 the shaft 18 isallowed to shift from its normal position as the finger 20 secured tothe outer face of the slide bearings 17 slips into the opening 15provided in the stand 16. Simultaneously the small beveled gear 7 willbe thrown out of engagement with the large beveled gear 6 whereupon therotation of said roller 3 will cease.

So that the spindle 9 upon which the roller 3 is mounted'will benormally held in downward position against a certain predeterminedresistance, a lever 21 is secured to the spindle 13 and extends forward,said lever being provided with a weight 22 at its forward end,whichweight will have a tendency to hold the rods 10 normally in lowcredposition, only to be raised, as above described, when too much cotton orany solid object begins to pass under said roller 3.

The rods 10 are guided in their vertical movement by means of guides orholders 23 which are secured one to each of the rear corners of saidfeed plate 2.

Although I have specifically described the novel features ofconstruction, combination and arrangement of the several parts of myinvention, yet I do not confine myself to such construction, but reserveand may ex ercise the right to make such changes therein as do notdepart fromthe spirit of the appended claim.

It will be understood that when the roller 3 encounters an obstructionor an extra thickness of cotton, the said roller will come to a state ofrest as hereinbefore described, while the gear wheel 7 continues torotate with the shaft 18. Inasmuch as the upper end of the arm 14: is atthis time belowthe inner end of the finger 20' and the gear wheel 6 isat a state of rest, the teeth of the gear wheel 6 will have a tendencyto push against the edge of the gear wheel 7 and thus the said gearwheel 7 is forced away from the gear wheel 6 and the roller remains atrest while the shaft 18 and the gear wheel 7 continue to rotate.

Having described my invention, What I claim as new, is:

In combination with a cotton card having a feed plate, a stop motioncomprising a shaft journaled above the feed plate and carrying theroller which is located above the feed plate, said shaft being free forvertical movement in its bearings, a gear wheel carried by the shaft, arod slidably mounted and arranged to move vertically with the shaft, alever suit-ably fulcrumed and pivotally connected at one end with saidrod,

an arm pivotally connected with the other I end of the lever, a standslidably receiving the upper end of said arm, a bearing slidably mountedin said stand and having a finger which normally lies against the sideof the said arm, a shaft journaled in the last mentioned bearing and agear wheel carried by the last mentioned shaft and normally meshing withthe first mentioned gear wheel.

In testimony whereof I afliX my signature in presence of two witnesses.
